Method for manufacturing automobile wheel spokes by utilizing steel tubes

Abstract

The invention discloses a method for manufacturing automobile wheel spokes by steel tubes. Steel tubes are respectively sheathed and fixed outside of a first mould and a second mould; the principal axis of a spinning machine drives the first mould and the steel tube fixed on the first mould to rotate; the rotary wheel of the spinning machine applies preset pressure on the outer wall of the steel tube along the radial direction of the steel tube from the outer part of the steel tube; the rotary wheel of the spinning machine and the second mould move along the axial direction of the steel tube according to the preset rhythm, so that the inner wall of the steel tube sticks to the surface of the first mould and the second mould to form a shaping piece with the inner wall shape of two wheel spokes; along the radial direction of the shaping piece, the shaping piece is cut into two symmetrical singletons; a press and a third mould respectively cut the cutting surfaces of the two singletons into planes, so that the two singletons respectively form two molded pieces with the spoke shape; and the mold pieces are manufactured into the finished product of the spoke by punching, wind hole punching, turning, chambering and the like. The invention does not generate waste in the manufacturing process, furthest saves raw materials and conforms to the requirements of modern energy saving and environment protection.

Description

technical field [0001] The invention relates to a method for manufacturing wheel spokes, in particular to a method for manufacturing automobile wheel spokes by using steel pipes. Background technique [0002] Truck and passenger car wheels are generally divided into two types: wheels with inner tubes and wheels without tubes. A tubed wheel generally consists of spokes, a rim and a retaining ring; a tubeless wheel consists of spokes and a rim. The wheel is manufactured separately from the spokes and the rim, which are then welded together. The shape of the spokes is a truncated cone, the plane of the truncated cone is the mounting surface, and the cone has cooling holes. The spokes are the connecting parts between the rim and the axle, and play the role of transmitting supporting loads, rotating loads and various alternating loads. Due to the important role of the spokes on the vehicle, the material thickness of the connection between the spokes and the axle, that is, the ...

Therefore, the four corners on the square block material and the washed-out middle hole round cake are waste materials. According to calculations, the material utilization rate of this material method is the highest at about 82%, that is to say, about 28% are waste materials, and waste materials The price of the finished product is far lower than that of the finished material, which not only increases the cost, but also wastes precious resources
